A new generation digital ionosonde, a Vertical Incidence Pulsed Ionospheric Radar (VIPIR) was installed at the NASA Wallops Island Flight Facility in Virginia and saw first operation in 2007. The VIPIR features dramatic improvements in ionosonde and radar system design, including multiple phase-coherent, fully digital receivers, improved antenna designs, and higher data resolution. This produces markedly improved ionograms. From the mid 1980's through today, NASA Wallops hosts a first generation digital ionosonde, a US Air Force Digital Ionospheric Sounding System or Digisonde 256. Phase coherent digital sampling of analog receiver output, digital data storage and automated real time ionogram scaling allowed spread-F quantification and use of the data for launch decisions. In the 1970's and early 1980's an analog ionosonde, at Wallops recorded data on photographic film. Hourly characteristics were later scaled by hand, with spread-F being qualitatively identified. Recently, select periods of film ionograms have been digitized by NOAA/NGDC and are available in electronic format. This presentation compares spread-F observations made with three generations of ionospheric sounding equipment operated at the NASA Wallops Island Flight Facility. Comparison of ionogram data from both VIPIR and Digisonde ionosondes during several different events reveals newly observed mid-latitude spread- F features.
